Scope of crumb rubber of various fractions

Essentially, crumb rubber - is highly comminuted tires, which fractions have acquired in the processing of various forms and sizes.But eventually they retain the characteristics of the starting material - elasticity molecular structure.Depending on the rubber crumb manufacturing processes can be given, and some additional features that extend the scope of its application.

The raw materials are mainly used tires that have become unusable.The method of processing may be different - the chemical, physical and chemical.Can devulcanization (partial) of the upper layer.All this affects the specific characteristics of the final product.

Features

• Relative mechanical purity crumbs.The presence of metals is not more than 0.03% and other materials - 2%.
• Density (bulk) - within 300 - 350 g / dm3.
• Maximum humidity - 0.95%.

Scope fines crumbs

0,2 - 0,45 mm

used as additives, generally to compositions for the production of rubber goods, to increase their flexural strength, shockproof properties, wear resistance.

0,45 - 0,6 mm

most often used in enterprises engaged in the manufacture of footwear.The proportion of such an additive powder may be up to 65% of the total weight of raw materials.

0,6 - 1 mm

more widely used in the production of building materials.For example, in the manufacture of certain types of coatings for roofing, waterproofing agents surfaces.Used as an additive in formulations for the preparation of mixtures, such as asphalt concrete.

often used as an ingredient in the compositions to increase strength and durability of the roadway that it prevents the occurrence of cracks, the occurrence of local deformations, allowing to equip the coating in regions with low temperatures.

Another area of ​​use - eliminating the consequences of accidents involving the diversion of petrochemical products.It plays a role in the liquidation of absorbent patches of oil and oil spilled on the ground.

used in the production of various corrosion-resistant, sound-proof, vibration-absorbing means.Included in the various cements and pastes.

rubber crumb used:

• in the form of rolls, mats as flooring in children's, sports fields, a filler for boxing bags and pears and the like.In combination with a solid cord baby is used to make durable Triplex coatings, various rugs and paths.
• In the manufacture of building materials - for the production of decorative products, as well as materials for various coatings, including and the roofing.For example, rolls of polyurethane and bitumen.On sale there are tiles that can be laid out the same garden paths.
• During manufacture roofing rubber crumb is used as a "spreading" of the upper layer.This treatment gives additional moisture repellent, anti-corrosion properties of materials.
• is introduced into the means used for sealing various joints and seams.
• In the production of fiber-reinforced concrete (arrangement of self-leveling floors, filling the basement) and in other cases.

about crumb rubber can write a lot, but all other fields of application are mainly for industrial use (bridge engineering, pipeline construction, automotive and so on).
